In China, we can see white trash, common throw the waste battery status, protect the environment, 500 - word composition. Well look at Japan, Japans battery and white trash are through strict processing, no breach of the garbage disposal in China. I once read an article, the article mentioned in humans to Mars, lets not say whether there are suitable for human survival on Marss atmosphere, can the living. Now we have already seen, the earth has been destroyed by us so, we not only not repent, dont have to destroy another planet?

If stubbornly wait until the whole universe are we break up, we dont know to repentance? To see our mother river - the Yellow River! It used to be so spectacular, so great, is our Chinese peoples pride, between the two generations, however, you see, now whats the mother river? And a mighty momentum before? Later we if asked about Yellow River between the two generations, we how to answer, again to see the big forest into a desert, all desire become the real "Yellow River", we must continue to damage the earth? We hate Japanese dont like Japan, but please put down hatred of learning how to learn Japanese environmental protection?

Japan is the largest country in the amount of wood, but never cut down their own trees, are imported timber in foreign countries, Japan is the largest country in the world forest area accounted for the proportion. There will be a high pollution projects on foreign production. Read this, Im afraid you will scold the Japanese are trying, but its not just proves that Japan is one of the most importance to the state environmental protection?

Protect the environment, starts from me!!!!!! How many times we shout the slogan, but we have to implement? The slogan was initially we shout out, but we never have the real action, and this slogan as a basic national policy by Japan, the implementation of the little hole. This not only make the Japanese environment better, or Japan become the least amount of pollution in the air.

So Japan seems really shameless, despicable! But this is our most the place. Take a look at our central news, headlines which which where leadership is always a meeting, what was said at the meeting, but that many are just fallen on deaf ears, which can truly implement good, is all lip service, had forgot. But foreign headlines always where where what happened, for help, for the common people for the real benefits. This is the difference between China and Japan. We sell wood at a low price to foreign countries every year, and then to spend hundreds of thousands of millions of the soil and water conservation management. This is the difference between China and Japan. The frequency of the Yellow River burst its Banks over the years more and more frequent, we do not pay attention to the Yellow River is not protected and the consequences of planted?

I say this is not I...... today, I really love our country. Really hope our country can better. I described above is the living example, we see is true, to everyone. Over the years we in the development of science and technology has obtained the very good fruit, but we on environmental protection and began at least fifty years of distance in the world, do we still shouldnt have a good look at what? I said these are want you to look at our countrys environmental protection problems, lets put the protection of the environment, starts from me "to carry out the point, make our country more beautiful, more beautiful.

I am a middle school student, not how good literary grace, not how beautiful words, it can write this. But I really hope our country better, become the pride of our all Chinese people!!!!!!

It is very urgent to protect the environment,! Lets action, and work together for the motherland tomorrow.

在中国，我们可以普遍的看到白色垃圾满天飞，废电池乱扔的状况，保护环境作文500字。我们再看看日本，日本的电池和白色垃圾都是经过严密处理的，完全没有上述中国垃圾处理上的疏漏。我曾经看过一篇文章，文章中提到人类移居火星的事，咱们先不说火星上是否有适合人类生存的大气，能不能活人。现在我们已经看到了，地球已经被我们破坏成这样了，我们不仅不悔改，难道还要再破坏另一个星球吗?

是不是硬要等到整个宇宙都被我们破坏完了，我们才知道悔改?再看看我们的母亲河——黄河!它曾经是那么壮观，那么伟大，是我们炎黄祖孙的骄傲，可是，你们看看，现在的母亲河是什么样子?还有以前磅礴的气势吗?以后我们的祖孙如果问起黄河，我们又该如何作答，眼看着大片的森林变成荒漠，条条清流变成真正的“黄河”，我们还要将地球继续破坏下去吗?我们恨日本不喜欢日本，但是请先将仇恨放下学习学习日本的环境保护好么?

日本是用木材量最大的国家，但是却从不砍伐自己国家的树木，都是进口的国外的木材，日本是全世界森林面积占国土比例最大的国家。将有高污染的工程全放到国外生产。读到这里，恐怕大家免不了要骂日本人心机重，但是这不正好证明了日本是最重视国家环境保护的吗?

保护环境，从我做起!!!这句口号我们喊了多少遍了，可是我们有落实过吗?这个口号最初还是我们喊出来的，但是我们从来都没有真正的行动起来，这个口号被日本当做了基本国策，落实的没有一点漏洞。这不仅使日本的环境变好起来了，还是日本成为了大气污染最少的国家。

这么看来日本好似真的很无耻，卑鄙!但是这却是我们最该学的地方。看看我们中央新闻，头版头条总是哪个哪个领导在哪开会，会上说了些什么，但是那很多都只是耳旁风，有哪个能正真落实好的，全都是嘴上说说，过了就忘了。但是外国头版头条总是哪里哪里发生了什么，都是求帮助的，真正为老百姓谋的了福利 。这就是中日之间的差别。每年我们将木材低价卖给外国，然后又要花几十万几百万把水土治理好。这就是中日的差别。这些年来黄河决堤的频率越来越频繁，这不都是我们不注意黄河保护而种下的恶果吗?

我今天说这些并不是我崇洋媚外，我真的很爱我们的国家。真的希望我们的国家能越变越好。我上面描述的都是我们看到的鲜活的例子，都是真正的，大家有目共睹的。这些年来我们在科技发展上取得了很不错的硕果，但是在环境保护上我们却与世界上拉开了至少五十年的距离，难道我们还不该好好反思一下吗?我说这些是想让大家注视一下我们国家的环境保护问题，让我们把“环境保护，从我做起”落实到点上，让我们的国家变得更美，更漂亮。

我是个中学生，没有多么好的文采，没有多么华丽的词语，这能写到这了。但是我真的希望我们的国家变得更好，成为我们所有中国人的骄傲!!!

保护环境，刻不容缓!让我们行动起来，为了祖国的明天而一起努力。

昨天，我妈妈给我买了一本书，是关于动物的，接下来我就给大家大概说一下吧。

我花了一小时把那本书看完了，看完之后我就知道了我们要保护动物，因为里面讲到这样一件事，从前，在一个村子里的人，全部信仰动物之神，但有一个人不信，他就去抓了几只鸽子杀了，之后的几天里，那个人突然死亡，大家都信他是被动物之神杀死的，之后就没人再抓动物了。

看完这个故事，还真应了我们语文书上的一句话：降临到动物身上的，终究会降临到人们身上。

老虎是生活在食物链顶端的一种动物，它关系到整个生物链的平衡。因此，保护老虎不单单是保护老虎这么一个物种的问题，而是保护整个食物链完整性的问题。

目前分布于我国的四个老虎亚种(东北虎、华南虎、孟加拉虎和印支虎)中，惟有华南虎是中国独有的。19世纪以前，华南虎曾经广泛分布于以我国东南部为主的国内广大地区。20世纪后，由于自然环境变迁、战乱纷扰及人类活动影响等多方面的原因，华南虎的分布区域不断受到挤压，分布地域面积逐渐缩校直至上个世纪80年代以前，由于捕猎和砍伐森林等活动，使华南虎赖以生存的栖息地受到破坏，华南虎的数量急剧减少。

据以往调查估算，目前中国处于野生状态的华南虎仅有20至30只，养殖在中国动物园里的数量也仅有60只，这仪数量比大熊猫还要稀少。在最近的一次野外考察中，甚至没有发现活的野生华南虎个体，华南虎已接近物种灭绝的边缘。

国家林业局全国野生动植物研究与发展中心的副研究员陆军介绍说，由于动物园中的数量有限，用于交配的华南虎之间的血缘关系越来越亲近，目前有的新产虎崽已经开始出现短尾(尾巴短一结)的现象。毫无疑问，如果任由这一趋势发展下去，在不久的将来，这一世界最濒危动物将不复存在。

透过虎类这一典型的例子，我们更应该保护动物，从自己做起，从他人做起，从身边的小事做起。让我们行动起来保护野生动物，共建和平家园世界将变得更美好。

许多野生动物正面临灭绝的危险，因为它们生活的环境已经发生了巨大的变化。例如，随着城市的发展，杀虫剂的使用和严重的污染，他们的生活区域变得越来越狭小。许多野生动物现在面临食物危机。同时，人类为了获取皮毛、皮肤、角、牙和肉而捕杀物种。

为了保护我们的生态资源，人们应该意识到任何物种的损失至少是知识的源泉和自然美的源泉。因此，本应采取以下措施：制订污染标准以降低有毒物质;严禁杀害某些稀有物种;应建立国家公园作为野生动物，保护区。

只有人类采取一些激烈的措施，野生动物才能被保存下来。

自古以来，动物就是人类的朋友，它们心甘情愿的为人类做奴隶，可是，我前些天在网上看到的一组让人触目惊心的图片却令我久久不能平静：

在各大商场里，狐皮包、虎皮大衣、鳄鱼皮皮鞋、手提包总是最耀眼的奢侈品。在各大餐馆中，往往不难看到桌上是熊掌、蛇肉、猴脑等野味。在许多人看来，这只不过是一件件豪华的大衣、精美的奢侈品，是一席席美味的宴席，可是，你们可曾想过它们也是一条条鲜活的生命啊!我看见这些东西，就仿佛看见了一双双沾满鲜血的双手，更是看见了未来因缺少动物资源而一片荒芜的大地;仿佛听到了一声沉闷的枪声过后一只只动物倒地的闷响和随之而来的惨烈的叫声……这难道就是人类对待朋友的态度吗?

其实动物是我们人类最忠实的朋友。比如大象，在我们亚洲的某个动物园中，有一个饲养员天天和大象在一起，他们的关系非常融洽，感情越来越深。终于有一天，老饲养员因年老体弱，体力不支而告老回乡。大象因此不吃不喝，饿得面黄肌瘦，一连病了好几天，院长十分焦急，只好让老饲养员回来。谁知奇迹发生了，饲养员一回来，大象的病竟然奇迹般地好了。由此看来，动物也有灵性，有着与人类相同的情感，大象的忠实恰恰证明了这一点。那我们人类还有什么理由去伤害它们呢。

我呼吁：请不要再残害动物们了，它们和我们一样，也是有灵性，也是有家庭的，都是大自然的子女。贪婪的人类啊!不要只顾自己的利益，而忽略了大自然的感受。不要为了一张皮，一份金钱，而去残杀那些无辜的生命。

因此我倡议：全人类行动起来，权衡利弊，克制自己，不去做无谓的杀生。保护动物，与动物和平共处，并将宠物放生。向更多的人宣传保护动物，向他们陈述利害关系，让他们也一起加入保护动物的行动里来。

人类啊!清醒吧!破坏了生态平衡是多么的可怕。地震、海啸、冰灾已经是大自然对我们的严厉惩罚，难道你们还要继续无知地贪婪下去吗?

When the Arctic Ocean freezes over in the autumn, polar bears set off in search of their favorite meals: fatty ringed seals and bearded seals. By the summer, the sea ice begins to melt and break apart. Deprived of access to the tasty seals, polar bears spend the summer fasting. At least, thats whats supposed to happen. As the planet warms, the warmer ice-free season is getting longer and longer. So whats a hungry bear to do?

Scientists once thought that polar bears might survive by supplementing their pinniped diet by turning to terrestrial foods like snow geese, their eggs and caribou.

"Weve had this debate in the literature about whether terrestrial foods are nutritionally relevant to polar bears during the on-land season when the ice has melted."

University of Alberta biologist Nick Pilfold.

"And weve known for a long time, going back to research in the early 70s, even going to back to early explorer logs, that polar bears will consume terrestrial based foods. But the debate was always whether those foods actually add up, energetically." In other words, do these substitutes provide enough nutrition to make up for the lost seals?

To find out, Pilfold and his colleagues estimated the weight lost each day by polar bears in the wilds of western Hudson Bay during the ice-free season, when they could ostensibly be chowing down on terrestrial foods. Then they compared that to the weight lost by bears that are temporarily held in Manitobas Polar Bear Alert Program.

While captive, the bears do not eat. They drop about one kilogram each day. But the wild bears, who had access to the Arctic snack bar, lost the same amount of weight each day. The results are in the journal Physiological and Biochemical Zoology.

"Which is really saying that the terrestrial foods do not have dense enough energy to offset the mass loss. So this idea that bears can just switch from eating sea ice–based food to land food and thats going to help supplement against longer ice-free seasons, that really doesnt show up in the data."

The problem is that polar bears evolved to rely on the marine diet.

"The food on land is protein and carbohydrate based, and the food the polar bears really focus on is fat. Fat is the name of the game for these bears; theyre highly adapted to absorbing that fat into their system and putting it onto their body as body mass, so they can fast on it later on. And the only thing thats going to provide them with that type of fat are marine mammals. And they can only access those marine mammals when theres sea ice."

Adult males can go eight months without food. But younger, sub-adult bears, which are no longer nursing and must hunt, cant last as long without sea ice. So as the Arctic warms, younger polar bears will disproportionately die out. Leaving the species survival in doubt.

北冰洋在秋季结冰以后，北极熊就会出发去寻求它们最喜欢的食物：富含脂肪的海豹和胡子海豹。海冰在夏季开始融化断裂。这使北极熊在夏季无法吃到美味的海豹，所以它们进入禁食期。至少，情况应该是这样。但是由于地球变暖，温暖的无冰季节越来越长。那饥饿的北极熊要怎么办?

科学家曾经认为，北极熊可能会转向陆地上的食物来补充它们对鳍足类动物饮食的需求，进而生存下去，这些陆地食物包括雪雁、雪雁蛋和北美驯鹿。

“文献中有过这类辩论，即在寒冷融化时陆地食物是否能满足北极熊的营养需求。”

尼克·皮尔福德是加拿大阿尔伯塔大学的生物学家。

“通过上世纪70年代初的研究，还有早期的探险者日志，我们很早以前就知道，北极熊会以陆地食物为食。但是辩论的焦点在于，这些食物是否能增加北极熊的能量。”换句话说，这些替代食物能否为北极熊提供足够的营养，弥补不能进食海豹带来的损失?

为了解开这个疑惑，皮尔福德及同事对西哈德逊湾荒野地区的北极熊在无冰季期间每天失掉的体重进行了估算，从表面上看，北极熊在这段时间食用了陆地食物。随后，他们将这一数据与通过马尼托巴北极熊预警计划暂时捕得的北极熊所失掉的体重进行了对比。

在被关期间，北极熊不吃东西。它们的体重每天大约下降1公斤。虽然野生北极熊能享用北极“小吃”，但是它们的体重每天也同样会下降1公斤。这一研究结果发表在《生理学和生化动物学》期刊上。

“显然结果表明，陆地食物不能为北极熊提供足以抵消大量损失的能量。所以，北极熊可以从食用海冰下面的食物转向食用陆地食物，并帮助它们对抗日益延长的无冰季这个观点，并没有在这项数据中得到证明。”

问题是，北极熊进化成了依靠海洋食物的动物。

“陆地食物以蛋白质和碳水化合物为基础，而北极熊需要的食物以脂肪为主。脂肪是这些熊真正需要的东西;它们高度适应的情况是，将脂肪吸收进它们的系统中，然后把这些脂肪放在身上以增加体重，这样它们之后就可以依靠这些脂肪来度过禁食期。唯一能提供给北极熊这种脂肪的就是海洋哺乳动物。但是它们只能在有海冰时食用到这些海洋哺乳动物。”

成年北极熊可以8个月不进食。但是小一些的未成年北极熊已经不再被哺育，它们必须要去猎食，可是它们不能在漫长的无冰季期间一直不进食。所以，随着北极地区变暖，较小的北极熊将会大批死亡。这使这些物种的生存成为问题。

Advice on Protecting Wild Animal

Many animals are in danger of dying out。 As is shown in the chart， we can see the number of animal species decreases faster and faster and this trend will continue。 From 1980 to 2010， at least 1 million animal species have disappeared。 Worse still， more and more wild animals are in great danger。 It is not a piece of sensational news; it is a fact， a harsh reality。 Unfortunately， we may not see these animals in the near future。

很多动物频临灭绝的危险。图表显示，我们能够看到动物物种数量下降的速度越来越快，而且这种趋势将会持续下去。从1980年到2010年，至少有100万动物物种已经消失。更糟糕的是，越来越多的野生动物处于巨大的危险中。这不是一则耸人听闻的新闻，这是一个事实，一个残酷的事实。不幸的是，将来我们可能看不到这些动物了。

From the second picture， we can find some reasons。 Why is the number of animal species declining year by year? Apparently animals have bee victims of fashion industry。 Animal skin has been used to make fashionable clothes and these clothes sell at a high price。 So some greedy people begin to kill animals in a large quantity。 This irresponsible behavior not only breaks the balance of nature but also endangers the living environment of human beings。

从第二幅图我们能够找到一些原因。为什么动物物种的数量一年年的减少呢?显然，动物成为了时尚工业的受害者。动物的皮被用来做时髦的衣服，而且这些衣服都是高价出售。因此，一些贪婪的人就开始超多屠杀动物。这种不负职责的行为不仅仅打破了自然的平衡，而且使人类居住环境陷入危险。

As far as I am concerned， something must be done to stop this illegal action。 We believe "no buying， no killing"。 First， we must make concerning laws to protect these animals in danger。 Second， we must take some measures to protect animals effectively。 Animals are our friends and part of our environment。 Third， we should raise peoples awareness to protect animals and our environment。 In this way， we can build a harmonious society and ensure a sustainable development。

在我看来，我们务必要做些什么来阻止这种违法行为。我相信“没有买，就没有杀”。首先，我们务必制定有关法律来保护这些处于危险中的动物。其次，我们务必采取一些措施有效的保护动物。动物是人类的朋友，也是我们环境的一部分。再次，我们就应提高人们保护动物和环境的意识。这样一来，我们就能够建立一个和谐的社会，确保其可持续发展。

Let’s Do Something to Save Our Environment

It is recently reported that some rivers and lakes have dried up in South China. A lot of fishes died. The bottoms of the rivers and lakes have become grass land. The water is becoming less and less because of the bad weather.

So everyone should do something to save our environment. First, we should save every drop of water, such as turning off the taps after using it and recycling the water. For example, we can water the plants and clean the rest room with our used water. Second, we should save energy, such as less turning on the lights and turning off the lights when we leave;Do more walking, more bicycling and less driving and so on. Third, we should ask our government to control the pollution from the factories.

Let’s act now from everything to save our environment. Don’t let our tears be the last drop of water in the world!

你也许看了会说：“动物还很多，好象不需要保护;并且有动物园，它就承担了此向任务，不需要我们吧?何况有些动物就该杀!比如北极熊，棕熊，特别是狼啊，鲨鱼之类的。它们总是吃人，咬人。难不成还要保护它们??还有，动物凭什么和我们相提并论?它很聪明吗?不见得吧?”

如果你的想法与此相同。那我有权给动物辩论：“你说有动物园是吧!动物园里的动物还叫动物，有的年寿体衰，有的被人整的不是样子，并且没有自由，算什么动物，还有，什么叫做该杀如果有某种动物比人进化的更早，更好，开始杀人类，将人类关进笼子里，那么已经成了动物得人类有什么感想囔?并且文件真明有的动物的思考能力与人相当。
